Say Baleen!

Creative Commons License
Baleen whales have a specialized filter feeder system inside their mouths known as Baleen, which are columns of bristles attached to the whale's upper jaw. When a baleen whale consumes a large quantity of food such as krill, it uses the baleen plates to push the water out and retain the food. Baleen whales have been hunted for baleen in the past which was considered a cheaper substitute for ivory.

Happy World Smile Day!
